In this study, we examined situation of collection and integration of evacuees records, intentions of public employees to support evacuees at non-designated evacuation shelters and supporting functions of designated evacuation shelters for non-designated evacuation shelters. In Mashiki town in the 2016 Kumamoto earthquake, evacuees’ records were collected but it took time to integrate the information on evacuees. In addition, although designated evacuation shelters partly functioned as support bases, non-designated evacuation shelters tended to receive support by organizations with whom they had relationship before the earthquake.
